For the rad, use Toyota OEM Super Long Life coolant from the dealer. Do not use the recommended Dex-Cool in the onwers manual.
For the gearbox, use a straight Toyota 75W GL-4 only. Do not use the GM recommended 75w-85 in the owners manual, your gearbox will become more notchy and will be grinding and catching when cold. If the Toyota oil is too expensive use an equivalent synthetic straight 75w. There is no filter, just drain and fill until it starts to drip out the fill hole. Holds about 2 liters
For the engine you can use any 0w-20 or 5w-20 synthetic, I use Mobil1 and sometime I use Toyota synthetic 0w20 from the dealer and a Toyota OEM filter or sonetimes a K&N if I can find a sale.
For spark plugs use original Denso 3444 part # SC20HR11 like these below. They come pre-gapped and ready to install.https://www.amazon.com/Denso-3444-Spark ... iac%3Avibe
Besides that nothing really breaks down other than the dreaded radio volume/tuner knobs. You also need to pay attention to the rear brakes and have them serviced once a year if you live in the rust belt. Remove the slide pins, grease them and put them back, rear brakes have a tendency to seize if left unserviced.
